Bruce is 4 times as old as Indy. 6 years ago, Bruce was 6 times as old as Indy. How old is bruce?

Answers

Answer:

60

Step-by-step explanation:

Bruce is 4 times as old as Indy

b = 4i

6 years ago, Bruce was 6 times as old as Indy

b - 6 = 6(i - 6)

b - 6 = 6i - 36

Substitute for b = 4i

4i - 6 = 6i - 36

Subtract 4i from both sides

-6 = 2i - 36

Add 36 to both sides

30 = 2i

Divide both sides by 2

15 = i

Since b = 4i

b = 4(15)

b = 60

Which of these strategies would eliminate a variable in the system of equations?
2x — бу = 6
6x – 4y = 2

Answers

Answer: A and B


Explanation: I’ll use A as an example. When you multiply the bottom equation by -3/2, the equation becomes: -9x+6y=-3. Then, proceed to add the equations. Look at X and Y in both equations: do the Y variables in both equations equal to 0 when added together? Yes, because -6y+6y=0! Therefore, you can eliminate y in these two equations.

Answer:

49

Step-by-step explanation:

4^3=64

5(-3)=-15

64+(-15)=49

Answer:

49

Step-by-step explanation:

First, because of the order of operations, you would do 4^3 (or four to the power of three) first to get 64. 5×-3 is equal to -15, and a positive number plus a negative number is just that positive number minus a positive version of the negative number, if that even makes sense. Basically, 35 + -2 would be equal to 35-2. 64-15 is equal to 49, which is your answer!

Find m∠ABD and m∠CBD given m∠ABC = 111∘.

Answers

Answer:

m∠ABD = 88º

m∠CBD = 23º

Step-by-step explanation:

(-10x + 58) + (6x + 41) = 111

Combine like terms

-4x + 99 = 111

Subtract 99 from both sides

-4x = 12

Divide both sides by -4

x = -3

------------------------

m∠ABD = -10x + 58

m∠ABD = -10(-3) + 58

m∠ABD =  = 30 + 58

m∠ABD = 88º

m∠CBD = 6x + 41

m∠CBD = 6(-3) + 41

m∠CBD = -18 + 41

m∠CBD = 23º

Answer:

88, 23

Step-by-step explanation:

<ABD + <DBC = <ABC

(-10x + 58) + (6x + 41) = 111

-10x + 58 + 6x + 41 = 111

99 - 4x = 111

-4x = 111-99

-4x = 12

x = 12/-4

x = -3

m∠ABD = -10x + 58

m∠ABD = -10(-3) + 58

m∠ABD =  = 30 + 58

m∠ABD = 88º

<DBC = 6x + 41 = 6*-3 + 41 = -18 + 41 = 23

Jim is repainting a free-throw key of a basketball court. the free-throw is made by combining a rectangle and a semicircle, as shown below. In order to know how much paint to purchase, Jim will determine the area of the free-throw key. What is the total area, to the nearest whole square foot, of the free-throw key shown in the diagram?

Answers

Answer:

285

Step-by-step explanation:

First find the area of the rectangle

A = l*w

A = 19*12 = 228

The find the area of the semicircle

A = 1/2 pi r^2

 We know the diameter is 12 so the radius is half the diameter so  1/2 (12) = 6

A = 1/2 (3.14)(6)^2

   = 1/2 (3.14) (36)

  = 56.52

Add the two areas together

225+56.52

284.52

a man in a boat rowing from light house whose height is 200 meter.he takes 2minutes to change the angle of elevation top of light house from 60⁰ and 45⁰ find speed of boat​

Answers

Answer:

The speed of the boat is approximately 0.704 m/s

Step-by-step explanation:

The time it takes the man in the boat to change the angle of elevation from 60° to 45°, t = 2 minutes = 120 seconds

The height of the light house = 200 m

Given that the angle of elevation is reducing, the direction of the man is away from the lighthouse

The initial distance of the man in the boat from the lighthouse = 200 m/(tan(60°)) = (200/√3) m

The final distance of the man in the boat from the lighthouse = 200 m/(tan(45°)) = 200 m

The distance traveled in 2 minutes, d = 200 m - (200/√3) m ≈ 84.53 m

The speed of the boat, v = d/t

∴ v = 84.53 m/(2 min × 60 s/min) ≈ 0.704 m/s

The speed of the boat, v ≈ 0.704 m/s.

The radius would be 10m.

Last month Maria hiked a total of 90 miles on two trails: a 5-mile mountain trail and a 10-mile canal trail. Let x represent the number of times Maria hiked the mountain trail, and let y represent the number of times Maria hiked the canal trail.

Which equation can be used to find the number of times Maria hiked each trail?

Answers

Answer:

5x+10y=90

Step-by-step explanation:

The equation that can be used to find the number of times Maria hiked each trail is 5x + 10y = 90.

How to depict the equation?

From the information, Maria hiked a total of 90 miles on two trails: a 5-mile mountain trail and a 10-mile canal trail.

x represent the number of times Maria hiked the mountain trail.

y represent the number of times Maria hiked the canal trail.

The equation will be:

= (5 × x) + (10 × y) = 90

= 5x + 10y = 90

The equation is 5x + 10y = 90.

What is the perimeter of this equilateral triangle?
Choices
4
20
40
60

Answers

Answer:

60

Step-by-step explanation:

If it is an equilateral triangle the sides are equal

24-x = 5x

Add x to each side

24-x+x = 5x+x

24 =6x

Divide by 6

24/6 =6x/6

4 =x

Each side is 5x or 5*4 = 20

Add the 3 equal sides

20+20+20 = 60

The perimeter is 60

Answer:

60

Step-by-step explanation:

In this case, to find the perimeter, we need to know the value of at least one side.

Since this triangle is equilateral, [tex]5x=24-x[/tex].

Adding x to both sides results in [tex]6x=24[/tex], and subsequently, [tex]x=4.[/tex]

Now that we know x equals 4, we can plug this into either 5x or 24-x and find out that one of the sides is 20.

Equilateral triangles have three equal sides, so 20 times 3, or 60, is the perimeter. I hope this helped!
